Does SP100 WANT to accomodate WirelessHART?

That appears to be the real issue. Several of the most technical members of the committee have explained that they believe that it is relatively minor impact on ISA100 to accommodate WirelessHART.
"I am not hearing anybody suggesting that SP100 should be adopting WirelessHART without any changes. The only option that's worth considering," Manges said, "is that ISA100 somehow accommodate WirelessHART despite the lack of backbone routing."
Dick Caro said, "But if the ISA100 network has backbone routing, and there are WirelessHART devices in the network, those devices would neither know or care."
